Practice worksheet for identifying and using colons and semicolons correctly in sentences.

To solve the problem, we need to determine whether a colon (`:`) or a semicolon (`;`) is needed in each sentence. Here's a breakdown of the rules for using colons and semicolons:

Colon (`:`)

- Used to introduce a list, an explanation, or a quotation.
- Often follows words like "as follows," "for example," "such as," or when introducing a definition or summary.

Semicolon (`;`)

- Used to connect two independent clauses that are closely related in thought.
- Can also be used in place of a comma with coordinating conjunctions (and, but, for, nor, or, so, yet) when the clauses are long or contain commas.

Now, let’s analyze each sentence:

---

1. I have a dental appointment on Wednesday at 2:00 PM.

- No punctuation is needed here because the sentence is complete and does not require a colon or semicolon.
- Answer: No punctuation.

---

2. Bob ate the pizza: Jane at the burgers.

- This sentence is incomplete and unclear. However, if we assume it means "Bob ate the pizza; Jane ate the burgers," then a semicolon is appropriate because both clauses are independent.
- Answer: Semicolon (`;`).

---

3. I went to the cottage: my sister went to the zoo.

- Both clauses are independent, and they are closely related. A semicolon is appropriate.
- Answer: Semicolon (`;`).

7. Tomorrow will start out sunny: however, rain is expected by the afternoon.

- The word "however" is a conjunctive adverb, which typically requires a semicolon before it when connecting two independent clauses.
